Safety warning The TEA1833DB1361 demo board input is connected to the mains voltage. Avoid touching the board while it is connected to the mains voltage and when it is in operation. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation from the mains phase using a fixed or variable transformer is always recommended. Figure 1 shows the symbols on how to recognize these devices. 019aab174 019aab173 a. Isolated Fig 1. UM10899 User manual b.
